Definitions

  • the present invention relates to a process and apparatus for assembling a bearing unit, and more particularly a wheel bearing unit for motor vehicles, having a hub and an angular antifriction bearing, at least one inner ring of the antifriction bearing being fixed axially by a bead formed on the end of the hub by means of plastic deformation.
  • This object may be achieved by a process and an apparatus as disclosed herein.
  • the force applied for the plastic deformation of the end of the hub is taken up, for example, in a proportion of 80% to 20% by the hub and the hub flange respectively. Because of this substantial support, the hub furthermore is not overstressed in the region of its flange. Finally, the apparatus is of simple construction and thus particularly well-suited for heavy everyday production use.
  • FIG. 1 shows a wheel bearing unit accommodated in a receiver in accordance with an embodiment of the invention.
  • FIG. 1 shows a wheel bearing unit comprising a hub 1 which is developed as a hollow hub and has a flange 2 for attachment to a motor vehicle or a wheel rim (not shown).
  • a hub 1 which is developed as a hollow hub and has a flange 2 for attachment to a motor vehicle or a wheel rim (not shown).
  • On the hub 1 there may be arranged, for instance, two ball bearing inner rings 3, 4 which, via balls 5, form an antifriction bearing of O-arrangement having a single-part outer ring 6 and separators 7.
  • the outer ring 6 also has an integrated fastening flange 8.
  • the hub 1 is provided at its end with a bead 9 for the form-locked assembly and the axial prestressing of the antifriction bearing.
  • the wheel bearing unit is inserted in a receiver 10 which supports the hub flange 2.
  • the hub is supported by a ram 11.
  • the receiver 10 and the ram 11 are supported resiliently, for instance by respective sets of springs 12, against a baseplate 13 for dividing the force which is applied for carrying out the plastic deformation of the bead 9.
  • a part of the deforming force in this example 20%, is conducted over the ball-bearing inner rings and the hub flange. In this way, it is assured that the antifriction bearing is not damaged during assembly, and further that the region of the flange 2 of the hub 1 is not excessively stressed.
